SoundPlank, like Acoustic Plasterboard, is a material you will have come across many times in soundproofing, perhaps you have read it in one of our guides, or a local installer has suggested it as a solution to your neighbour noise, or seen that it features on a specification for a housing or office refurbishment. It is also a truly universal product.

SoundPlank 19mm has a higher mass than both standard Plasterboard and Acoustic Plasterboard, and it is this mass that provides the reduction of airborne sound, reducing its transference from room to room by blocking sound energy. The brown paper facing does not receive a skim and plaster layer, and this is why it is primarily a part of full acoustic systems, as it sits behind Tecsound and Acoustic Plasterboard, which can be decorated over. To achieve the best possible result in soundproofing, you will need to incorporate SoundPlank into our acoustic systems, and you will find these in our 'Systems' tab above in all of our ceiling and wall soundproofing systems across a range of different solutions. Each offers methods of increasing the soundproofing performance by combining them alongside our MuteClip®.


  • 2400mm x 600mm x 19mm (1.44m2).
  • High-density plasterboard for protection against airborne noise.
  • Tapered or Straight edge.
  • Cannot decorate onto directly.
  • Incorporated into our MuteClip® Systems.


A minimum of 20 can only be ordered due to shipping, for quantities less than this, please see our half-size Acoustic Plasterboard in related products below. There can be a lead time of up to 5 days for this material, our team can help you with your arrangements on 01937 588 226.




This product contains a high level of mass, so if there any structural concerns you will want to consult a Structural Engineer to discuss your requirements.

The world of soundproofing and general construction presents an uncertain journey for those arriving fresh to the subject, there maybe terminology or use of acoustic testing figures that could appear confusing, and even if you are at a professional level, it is good to brush up to make sure you are making the right choice. We want to help you come to the right decision, so whether this is through the use of our guides or talking to a member of our team - we are here to help!

How to Soundproof a Wall or Ceiling

A combination of the following will always result in a much improved acoustic performance.


  • Mass: the addition of more substantial materials to reduce sound energy, for example, added layers combined with soundproof Plasterboard.
  • Separation: breaking contact with the surface or surfaces through the use of acoustic isolation clips or stud framing.
  • Damping: the reduction of vibration through the use of flexible, damping materials such as Tecsound.

When you are combining all the properties above you are creating a soundproofing system that is effective at reducing a more extensive range of sounds, and this works by covering the lower frequencies by separating the mass from the structure by suspending it away. Even with attaching substantial mass directly to the wall or ceiling, it is still attached, and is often lacking an air gap; this is fundamental in the isolation of sound. This, therefore, allows those low-frequency sounds and vibration (not just from machinery but the simple act of walking around, flicking a light switch or closing a door). We recognise the subjective nature of sound and how we react to each one, and that is why we offer so many variances in our systems. We understand that it is not always possible to incorporate significant losses of space with say, the introduction of a stud frame, so we provide different variances to suit what performance you need, your budget and thickness.

  • You will want to make sure that the surface you are applying to is flat to avoid any joints unsuccessfully matching up. 
  • When affixing SoundPlank you will want to use heavy duty fixings of 9 per board and remember to leave a 2-5mm gap from the adjacent surfaces.
  • Fix with tapered edge vertically
  • Fill all gaps, including the abutting of all joints and around the perimeter. The aim to make sure the surface is as airtight as possible as you are trying to reduce airflow that airborne noise transfers through, even the smallest of gaps.
  • Use a scrim tape on joins to provide a strong bond for skim plastering; it is essential to note that you require no additional lining paper for skimming, it is ready to go.

SoundPlank has an increased mass, which is an essential property in sound proofing when aiming to reduce airborne noise, this results in an improvement over standard Acoustic Plasterboard. When using in an acoustic system such as our MuteClip® Double Plus, we look to use a range of different materials with different mechanical properties and densities to help break down the sound more effectively.

Sound Plank cannot be used as a standalone product as it is not possible to decorate over the top; the paper front will receive plaster directly.

The brown paper finish will want to be facing into the room. If using a tapered edge, it will be the tapered edge facing into the room.
